The Pro-face 3.8-inch Touch Screen Model AST3301W-B1-D24 is a compact and reliable Human-Machine Interface (HMI) solution designed for a wide range of industrial automation applications. Operating on a DC24V power supply and classified as a standard-grade model, this device offers a durable and efficient interface for machine control and monitoring.

Display and Visual Features

The unit features a 3.8-inch monochrome LCD display with amber and red color options, providing clear visibility in various lighting conditions. With a resolution of 320×240 pixels (QVGA) and 8 levels of grayscale, the display ensures sharp and readable text, icons, and graphics. The backlighting is achieved through amber/red LEDs, which are factory-replaceable only, ensuring long-term reliability. Users can adjust the brightness in 16 levels directly through the touch panel, allowing for optimal viewing comfort in different environments.

Touch Panel and User Interface

The resistive analog touch panel offers precise and responsive input, enabling intuitive navigation and control even when used with gloves or in harsh industrial conditions. The interface is designed to reduce programming time, thanks to a rich library of pre-designed sample screens and 3D components provided by Pro-face. These resources allow users to create visually appealing and functional HMI screens quickly and efficiently.

Data Transfer and Upgrade Capabilities

Data transfer is simplified through the use of USB memory devices. This feature allows operators to easily update screen data in response to production line changes without the need for complex network setups. The system also supports easy upgrades, ensuring that the device can adapt to evolving operational requirements.

Security and Access Control

The AST3301W-B1-D24 incorporates robust security features to minimize on-site issues. A password management function allows administrators to set different access levels based on operator or manager roles. This ensures that only authorized personnel can view or interact with specific screens. For enhanced security, operators must enter both an ID and password before gaining access to machine controls.

Advanced Programming and Maintenance

One of the key advantages of this model is its ability to program and debug PLC logic directly through the GP without opening the control cabinet. The data pass-through function enables easy tuning of ladder logic programs and adjustment of data affected by production line changes. This feature significantly reduces downtime and maintenance effort.

Data Logging and Backup

The device supports efficient data backup and logging using USB memory or CF cards. Operators can generate daily and monthly reports quickly and easily. The CSV data conversion function allows users to modify PLC settings directly from the GP, streamlining data management and reporting processes.

Compatibility and Replacement

The GP/ST series is designed to be compatible with all previous GP series models, including the first-generation GP10 series. This ensures that existing screen data can be reused, saving time and resources during upgrades. The panel cut-out dimensions are also maintained across the product family, making physical replacement straightforward and hassle-free.

Efficiency-Enhancing Features

The AST3301W-B1-D24 is equipped with five key features designed to boost operational efficiency. The GP-Pro EX software, with its intuitive drag-and-drop and point-and-click interface, makes screen creation and logic programming accessible even for beginners. Advanced features such as 3D components, image fonts, and other tools further enhance the user experience.

Training and Remote Support

To reduce maintenance costs, the device supports video-based operation and maintenance instructions. This allows any operator to quickly learn how to use the system correctly. The PC simulation function enables users to test all GP operations—including screen transitions, D scripts, and logic scripts—on a computer without needing to transfer data to the actual device. Remote monitoring and control are also possible, allowing operators to view and manage GP screens from an office or other remote location. This facilitates real-time management and more efficient remote maintenance.

Error Visualization

By connecting controllers directly to the GP and using sample components, the system can display critical error information from the controller on the screen. This makes it easier for operators to identify and respond to issues quickly, reducing downtime and improving overall system reliability.
